### Question: What causes Sleep disorders in the elderly?
### Response: Sleep problems are common in the elderly. In general, older people need 30 to 60 minutes less sleep than younger people. Their sleep is less deep and more choppy than sleep in younger people. A healthy 70 year old may wake up four times during the night without it being due to disease.
Some causes or contributors to sleep disturbances in older adults include:
Alzheimer's disease Chronic disease, such as congestive heart failure Depression (depression is a common cause of sleep problems in people of all ages) Neurological conditions Pain caused by diseases such as arthritis Prescription drugs, recreational drugs, or alcohol Sedentary lifestyle Stimulants such as caffeine Urination at night
